1 Claim.

This invention relates to lamps, and an object is to produce a new and improved lamp, the illumihated part of which is adapted to rotate at the desired speed, and the lamp light may be controlled as desired for effecting a brighter or dimmer light.

Other objects of the invention reside in details of construction, arrangement and operation of the lamp shown for purposes of illustration on the accompanying drawing, in which:

Figure 1 is a side elevation of the lamp, a portion of the globe being broken away to show the interior thereof;

Figure 2 is a wiring diagram of the lamp; and

Figure 3 is an enlarged vertical sectional view showing the means by which the current is transmitted to the lamp through the upright shaft.

The illustrated embodiment of the invention comprises a base 10 on which is mounted an upright ligure 1l representing Atlas with one arm 12 thereof extended vertically upward. The gure 11 is suitably secured to the base 10 by screws 13. One leg of the iigure 11 and the upright arm 12 are provided with a bore 14, through which extends a tubular shaft 15. The upper end of the shaft projects beyond the upper end of the arm 12, and a suitable bearing 16 is provided in the arm 12 for the shaft l5. Fixed to the shaft l5 in any suitable manner and extending radially thereof, is a plurality of spring ngers 17 on which rest a globe 18. The globe 18 may be of any suitable translucent or transparent material, and may be suitably lined and colored to represent the world. An opening is provided in the lower end of the globe through which the upper end portion of the shaft l5 extends, and mounted on the upper end thereof is a lamp 19 for illuminating the globe 18.

Mechanism is provided for revolving the globe 18, and when the saine is lighted a pleasing effect is obtained. For the purpose of rotating the globe a suitable electric motor 20 is mounted in the inside of the base 10. The motor 20 has a driven shaft 21, which is operatively connected to the lower end of the shaft 15 for imparting rotation thereto. On the outside of the base 10 is a button 22, which may be rotated for increasing or diminishing the speed of rotation of the motor. The button 22 controls a rheostat 23, which, as shown in Figure 2, is connected by the lead 24 to the motor 20 in any suitable or well known manner.

As shown in Figure 3, wires 25 and 26 extend (Cl. Z110-10.1)

through the inside of the tubular shaft 15 to the lamp bulb 19. The lower ends of the wires 25 and 26 are connected respectively to spring ngers 27 and 28 disposed within a stationary housing 29. The fingers 27 and 28 engage respectively with ring conductors 30 and 31, from which lead the Wires 32 and 33. Manifestly, the current is continuously supplied to the bulb 19 through the rotatable shaft l5 while the latter is turning. A button 34 is provided for controlling the intensity of the light emitted by the bulb 19. The button 34 is operatively connected to a rheostat 35, which is suitably connected to one of the leads leading to the bulb 19.

From the above description it is apparent that the globe 18 may be rotated at any desired speed, and the speed may be manually controlled by the button 22. The globe may be rotated whether or not the lamp is lighted, and conversely the lamp 19 may be lighted without rotating the globe 18. The intensity of the light emitted from the lamp 19 is controlled by the button 34.

1t is to be understood that numerous changes.

in details of construction, arrangement and operation may be effected without departing from the spirit of the invention.

What I claim is new and desire to secure by Letters Patent is:

A device of the class described comprising a base, a figure on said base providing an upright support, a shaft extending upwardly through said support, a motor in said base for rotating said shaft, a bearing on said figure for the upper portion of said shaft, lateral fingers secured to said shaft adjacent the upper end thereof, a sphere having translucent walls loosely supported on said fingers, a lamp in said sphere mounted on said shaft, leads for said lamp extending through said shaft, a rheostat for controlling the current to said lamp, and means controlling the current to said motor.
